Sand casting aluminum is a type of aluminum casting produced through the sand mold casting method. It is widely used in industries such as machinery, construction, automotive, and more. In the production process of sand casting aluminum, it is important to avoid the following issues:

Mold Quality: The quality of the sand mold directly affects the quality of the casting. Therefore, it is essential to ensure that the mold meets the required specifications for compactness, permeability, and strength, to avoid issues such as porosity, sand inclusion, and deformation.

Ingot System Design: An improperly designed casting system can lead to poor metal fluidity, resulting in issues like gas pores and inclusions. Therefore, it is necessary to design the casting system reasonably based on the structure and dimensions of the casting, ensuring that the metal fluid can flow uniformly and stably into the sand mold.

Ingot temperature and time selection: Improper choices in temperature and time can lead to issues such as oxidation and inclusion in the metal liquid. Therefore, it is necessary to select the appropriate pouring temperature and time based on factors like the material and structure of the casting.

Mold and Equipment Maintenance: Inadequate maintenance of molds and equipment can lead to low production efficiency and unstable product quality. Therefore, it is essential to regularly inspect, maintain, and care for molds and equipment to ensure their proper operation.

Operation Standards: Inefficient operations can lead to low production efficiency and unstable product quality. Therefore, it is necessary to establish and enforce strict operation standards to ensure the smooth progress of the production process.
